I presume you're talking about the belt tensioner. There is no nut on the bearing portion and no nut on the pulley. The bolts just thread into the block and bracket. So if you have two bolts you're good. That's what I have on my '96, just looked.

When I unbolted the unit from the mount I heard something fall. when I started to install the bolt there is nothing in the mounting bracket to run the bolt into, just a round casting. Help

Find what fell. I go through it all the time. It isn't gone. It is in the hardest to get to place known to man. There are memes on facebook about this exact situation.

Take the doghouse off and look at the other side of the bracket. If something was there it will be that shaped indent. it is probably right behind the bracket on the intake or between the bracket and head.

It IS a small 10mm nut that fits into the indexed hole in the back of the mount BUT a very special nut ( a regular 10 mm nut won't fit because the shouldes of the nuts are too big. Dealer item $2.50!

Don't feel bad,10 mm nut is easy to lose particularly when you don't expect it to fall.
I just put a new heater core in my '97. Button her back up, before I let her off the ramps I top off the rad while running to burp the beast and then can't find the cap...

I got one of the last ones from a dealer. It is a VERY special nut that has shoulders about.030. Smaller than anything at the hardware store. That sucks.
